JOURNAL-BEARING FOR THE WARP-BEAMS OF LOOMS.

SSPECIFICATION forming part of Letters Patent No. 731,123, dated June16, 1903.

Application filed November 14, 1901. Serial No. 82,239. (No model.) 7 iTo aZZ whom it may concern.-

Be it known that I, OSCAR L. OWEN, a citizen of the United States,residing at VVhitinsville, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement inJournal-Bearings for the Warp-Beams of Looms, of which the following isa specification.

The journals of warp-beams require to be securely held in their hearingsto prevent the vibration of the warp-beams. The journalbcarings for thewarp-beam require to be open on the rear to permit of the placing of thewarp-beam on the journal-bearing. To secure these ends, I have designedajournalbearing consisting of two cylindrical blocks supported incylindrical hearings in the end frames. The blocks have thejournal-bearing for the warp-beam journal on one side of the blocks. Theblocks are, provided with weighted levers by which they may be turned,and stops are provided on the end frames to arrest the rotation of the,blocks at the desired points.

Figural is a top view, partly in section, illustrating thesupport of thebeam-shaft in the rotatable blocks. Fig. 2 is a side view of part of anend frame of a loom, showing the beam-shaft in section j ournaled in therotatableVbearing-block when in the locked position. Fig. 3 is a sideview of one of the end frames, showing the beam-journal in the unlockedposition.

In the drawings, A A indicate the end frames; at a, openings in the endframes forming the supports of the cylindrical journalblocks 1) b; ct a,the temporary supports of the journals of the warp-beam a a stop on theend frame, and a another stop on the frame. The blocks 17 b are ofcylindrical form to fit the openings at ain the end frames with asliding fit'and have on one end the flanges b b. They are provided atone side with the slot 5 in which the'journal c is supported within thecylindrical surface of the openings a a. The blocks 1) b have each theweighted lever 19 and the shoulder I)" extending from the flange b. Theblocks 12 b are preferably of more than twice the diameter of thejournal 0. The shaft d supports the warp-beam. The journals 0 c arepreferably turned down, so as to form theshoulder d, which bears againstthe flanged ends of the blocks 1) b.

When a warp-beam is to be placed on theloom, the blocksare turned in theopenings at a until the shoulder 19 is in contact with the stop ta Theslot 19 forming the bearing for the journal 0, is now opposite theopening a in the end frame. The warp-beam is now rolled inward until thejournals rest in the bearing 11 in the blocks 1) Z). The twobearing-blocks are 'now simultaneously turned into the position shown inFig. 1, when the journal-bearing is locked between the bearing in theblock and the bearing ofthe block in the end frame, the strain onthewarp-beam being resisted by the endframe.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent- 1. In a loom, the combination with the end frames andstops thereon, of cylindrical blocks supported in cylindrical bearingsin the end frames, stops formed on the blocks, means for rotating theblocks, and open journal-bearings for the warp-beam formed in the outerperipheral surfaces of the blocks, whereby when the blocks are rotatedin one direction the warp-beam will be moved inward and locked inposition and when rotated in the opposite direction the warp-beam willbe moved outward to facilitate its removal from the bearings, asdescribed.

2. In a loom, the combination with the end frames, the circular bearingsa a, the stops a a and the opening a in the end frames, of the rotatableblocks b b, the flange b on the blocks, the open journal-bearing in theperiphery of the blocks, the shoulder 5 and the weighted lever b wherebythe journals of the warp -beam may be placed into the journal-bearingsand secured against vibration by the partial rotation of thebearingblocks, as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

OSCAR L. OWEN.
